For high-capacity linear drainage across driveways and garage thresholds, the Traditional Galvanised Trench Grate and Frame delivers reliable, long-term performance where vehicle traffic is expected.

Manufactured from high-tensile steel and Hot-Dip Galvanised (R3) for superior corrosion resistance, this system is built to handle demanding outdoor conditions. The high-flow design efficiently captures and channels large volumes of water, making it ideal for managing runoff during heavy rain events.

Designed to be cast into concrete, this system forms a permanent and secure drainage solution. Installers will typically create a channel using formwork before pouring concrete, ensuring correct positioning and structural support. Using a grate and frame system also allows you to create a fall within the channel, improving water flow and overall drainage performance.

Supplied in modular lengths, it allows for seamless installation across longer drainage runs—making it a practical, cost-effective solution for residential and light commercial projects.

With same-day or next-day delivery available across the Sydney metro, you can keep your project moving without delays.

For areas with regular foot traffic, such as patios and pathways, we recommend upgrading to our Heelguard trench grate range for improved pedestrian safety and comfort.
